The ratio of estrogen to progesterone remains constant throughout pregnancy into labor. false/true
Lady_Fox [76]

False,

In order to start labor, estrogen increases and progesterone decreases.

Estrogens are a class of hormones that are essential for women's healthy sexual and reproductive development. They are sex hormones as well. The majority of estrogen hormones are produced by a woman's ovaries, however minor quantities are also produced in modest amounts by the adrenal glands and fat cells.

Progesterone is a member of the progestin drug class (female hormones). By lowering the level of estrogen in the uterus, it functions as a component of hormone replacement treatment. By substituting for the natural progesterone that some women lack, it helps to initiate menstruation.

If DNA can’t leave the nucleus, how do you think the DNA instructions get to the ribosomes in the cytoplasm?
koban [17]

Instructions in the DNA are first transcribed to RNA and the RNA is transported to the ribosome in the cytoplasm.

<h3>Transcription</h3>

Transcription is a process whereby the genetic instructions in the DNA of organisms are transcribed to RNA in the nucleus.

After transcription, the RNA which now carries the genetic codes is transported to the cytoplasm where it gets attached to the ribosome before the genetic codes are translated to their respective amino acids.

Identify Causes: What are some factors that might cause changes in the population of grasshoppers?
zubka84 [21]

Answer:

Empty calories may be grasshoppers' downfall.

Explanation:

Many insect populations are declining, and a provocative new hypothesis suggests one problem is that rising levels of atmospheric carbon dioxide (CO2) are making plants less nutritious. That could spell trouble not just for insects, but for plant eaters of all sizes.
